8 Claims. 1

This invention relates to valves, and particularly valves having a plurality of ports, and is adaptable for use in lines carrying high test gasoline, although it may be used with any kind of fluids.

With valves as constructed and in use at the present time the parts usually become worn after a short period of use due to the gasoline or other fluid drying and hardening the sealing parts and glands for lack of lubrication, causing leakage-around the operating shaft.

The principal object of the present invention is, therefore, to provide a valve constructed so that the fluid Within the valve will not contact with the shaft, bearings and actuating mechanisms of the valve.

Other objects of the invention are to provide flexible sealing means between the shaft chamber of the valve and the actuating parts thereof; to provide means for holding the valve in open or closed position; to provide means for lubricating the bearing surfaces and toggle members of the valve; and to provide a valve of simple construction which is economical to manufacture and efficient in operation.

Referring more in detail to the drawings:

l designates a valve embodying the features of my invention comprising a body or housing 2 8 containing a cylindrical bore 9 adapted to receive an actuating shaft 10, later described.

The hub 8 is provided with openings l I through whichtoggle members I2 are extended, and also with apertures [3 through which pins [4 are inserted for holding the shaft H) in the bore 9.

The shaft it is provided on its inner end with cams l5 and it forming annular grooves I1 and I 8 in said shaft. The groove [1 receives a ball like end [9 of the toggle member l2. I6 is provided with an outwardly flared portion 20 which extends into the groove I1, and the cam I5 is provided with a recess 2| opposite the outwardly flared portion 20 and of the same contour for a purpose later described. A yoke 22, having a socket is fitted over the outer end of the shaft Ill and fastened thereon by a fastening device such as a bolt 23. The shaft is provided through its center with a channel 24 through which lubrication may be supplied to the cam actuating mechanism. I also provide the oil channel with a Wick 25 as shown in Fig. 10, and ports 26 leading from the channel 24 to the cam groove ll.

Located within the ports 5, 6 and l in the body 2 and adapted to rest against the hub 8 of said body opposite said ports are poppet assemblies 21 constructed to open and close said ports by turning the shaft If! as later described.

Each poppet assembly includes a body portion 28 having upstanding posts 29 and 30. The body portion 28 has a channel 3| and is provided With ears 32 and 33 terminating in notches near the post 29. The body 28 also has notches 35 and the channel 3| extends through the body 26 providing an elongated slot 36 in a concave edge 2'! of the body member. Located between the posts 29 and 30 is a cylindrical poppet member 38 provided with ports 39 around its outer periphery, and the poppet has a head '16 provided with aboss 4! through which a transverse groove 42 is formed.

A lever 43 having a split end 44 is pivoted on a pin 45 extending through the ears 82 and 33 and through a. bearing 46 in said lever. A link 49 having a bearing 56 in one end is attached to the boss 4| in the poppet 38 by a pin 51. The

The cam 3 opposite end of the link is provided with a bearing 52 adapted to fit in the split end 44 of the lever 43 and is pivoted thereto by a pin 53 through bearing 54 in the split end of said lever.

A spring 55 is provided for exerting tension on the poppet member 38 to hold it in open position so that the edges of the chamber rest on the shoulders 56 of the body member of the poppet assembly. The spring 55 (see Fig. l) has a U-shaped end 58 which rests in the notches 34 in the body member 28. Coils 59 and 69 are provided on the spring adapted to fit over the respective ends of the pin 46. The opposite ends of the spring have hooks BI and 62 which engage the ends of the pin 53 which rests in the notches 35 when the poppet is in open position.

The head 4 of the poppet member 28 is provided with an annular rib 64 spaced from and extending slightly above an outer annular rib 65 of the poppet member and the space between forms an annular recess 66. The outer ends of the posts 29 and 38 are offset forming shoulders 61 and 68, for a purpose later described.

Port tfittings 69 are provided to fit in the port openings 5, 8 and I of the valve body. The fittings are provided with openings I6, having screw threads II adapted to receive fluid ducts (not shown). Around the outer periphery of the fittings are flanges I2 having notches I3 therein (see Fig. 4) The valve ports 5, 6 and I are provided with outwardly extending notched flanges I4 adapted to receive the notched port fittings 69. The respective notched flanges I2 and I4 have an annular groove I6 substantially midway of their length adapted to receive a split ring I? for holding the fittings in place (see Figs. 1 and 2). The ring I! is preferably made of spring material and in its normal position is smaller than the groove in the port fittings and flanges. When the ring is applied it is extended in the usual manner and when inserted over the groove snaps in place to hold the fittings securely to the valve body.

Located in the respective valve ports 5, 6 and I and adapted to fit against the face I8 of the port fittings 69 are rings I9 preferably made of rubber forming a seat for the poppet member 38. The valve seat I9 is also preferably formed with an annular lip 80, the lip beingflexible will follow the poppet down a short distance should there be a reverse flow of fluid thus making it impossible for a reverse flow of fluid to open the valve.

I also preferably provide between the valve seat I9 and the poppet 38 a load bearing ring 8| to facilitate seating of the valve. The ring is constructed so it has a depending flange 82 adapted to seat on the shoulders 61 and 68 of the posts 29 and 38 of the body of the poppet assembly while the outwardly flared portion 83 of the ring engages the top of said posts.

A principal feature of my invention is to avoid leakage of fluid to the actuating part of the valve mechanism and particularly the cam actuating mechanism in the shaft chamber. I, therefore, provide a cap 84 preferably made of rubber or other resilient material, for fitting aroundthe hub or sleeve member 8. The cap is preferably vulcanized to said sleeve and is provided with openings corresponding with the openings I I and I3 in said sleeve, through which the toggle members I2 and pins I4 are extended. The rubber cap fits tightly around the pins I4 to prevent leakage therearound. The shank of the toggles I2 is provided with peripheral ribs 85,, as best.

4 illustrated in Fig. 3, and the rubber cap is bonded, preferably by vulcanizing, thereto to provide a tight seal and yet allow for movement of the toggle members.

The toggles I2 also have ball shaped terminals 86 opposite the ends I9 for engaging in an opening 81 in the poppet lever 44. The toggles extend through the openings II in the hub 8 and the ball shaped ends I9 engaged in the cam groove I1 of the shaft I8. I also provide a ball shaped enlargement 88 on said toggles and a bearing 89 adapted to fit in the opening II in said hub and in which the ball portion 88 moves to facilitate movement of the toggles.

An internally screw-threaded flange fitting 89 is provided to be attached to the body 2 by screws or the like 90 engaging in threaded apertures 9| in the body of said valve for receiving a fluid inlet pipe (not shown). A gasket 92, preferably made of rubber, is provided to fit on a rounded shoulder 93 of the valve body for sealing the flange fitting to said body.

In assembling a device constructed as described, the shaft I0 is inserted in the chamber formed by the hub 8 and the locating pins l4 inserted through the opening I3 in said hub and the inner ends of said pins fitting in the groove I8 in said shaft. It will be noted that the ends of the pins are chamfered to facilitate location of the pin and their inner ends are adapted to fitin the groove I 8 thus allowing the shaft I 0 to rotate. The toggles I 2 are vulcanized in the rubber cap 85 and the cap inserted over the hub 8 and is vulcanized thereto. The cammed end I9 of the toggle will be inserted through the opening I I in the hub and is adapted to work in the groove ll of the shaft ID as shown in Fig. 1. The rubber cap will prevent fluid within the valve body from coming in contact with the shaft, shaft bearings and actuating cam of the valve actuating mechanism. The cap 84 is also provided with openings registering with the opening I3 in the hub for insertion of the pins I4 therethrough. The pins I4 will then extend slightly above the rubber cap as is also shown in Fig. 1.

The poppet assemblies 28 are then inserted in the ports 5, 6 and I in the valve body so that their edges 31 will contact the rubber cap around the sleeve 8. A recess 94 is provided in the edge 31 of the poppet assembly in which the chamfered ends of the locating pins I4 register. The cammed end86 of the toggle I2 extending through the rubber cap 84 is inserted in the opening 81 of the poppet lever 44 also as illustrated in Fig. 1.

After the poppet assemblies are inserted in the ports, the locating rings 8| are then inserted in the port openings so that they will contact the posts 29 and 38 of the poppet assembly and then the rubber seating ring I9 is placed over the locating ring so that its outer surface will bear against the port fittings 69 which are adapted to fit in the port openings. The valve body is preferably provided with an annular shoulder 95 at the outer shell of the valve housing around the port openings against which the valve seating ring rests I9 as shown in Fig. 1. The split snap ring 11 is then fitted in the groove I6 in the flanges of the fittings and the housing so that when the ring is snapped in place the port fittings will be held securely in place.

quickly assembled so that time is saved over the old manner of using screws to fasten the fittings in place. Such assembly greatly reduces break off of fittings when a p pe wrench is used in con- Joinder of the fittings by the snap ring provides greater resistance to torsion, and is venting 'le'akage and requirement of additional parts in assembling a valve of *"this' chract 1 After the insertion of the --poppet-assembliies aasket 92 maybe-placed over the -inlet port lon the -shoulder "93 of the body andthe fiange BSI fitting then applied theretoby the screws90$ Tlie ld entire valve may then -beconnected -to the inlet and outlet pipes (not shown) asdesired."
